Possible cause
Workaround
battery voltage of the
encoder is between 2.5V–
3.0V.
2. Use the multimeter to check
whether the external battery
voltage is less than 3.0V. If yes,
replace the battery.
3. Replace the battery when the
drive power is on. Otherwise,
encoder data may be lost.
Er02-a
Encoder fault–Encoder
overheating
The encoder feedback
temperature is higher than
the temperature threshold for
protection against
overheating.
1 Ensure the temperature
threshold for protection against
overheating is correct.
2. Stop the motor to decrease the
encoder temperature.
Er02-b
Encoder fault–Encoder
EEPROM writing error
If the motor is used with a
communication encoder, a
communication transmission
or data check error occurs
when the drive updates data
to the encoder EEPROM.
1. Ensure encoder cables are
connected properly and eliminate
the conditions that disturbs
encoder communication.
2. Make multiple writing tries. If
the fault is reported repeatedly,
replace the motor.
Er02-c
Encoder fault–No data in
encoder EEPROM
If the motor is used with a
communication encoder, no
data is found in the encoder
EEPROM when the motor
attempts to read data from it
during power-on.
1. Select the motor model based
on the setting of P0.00 and
execute the operation of writing
data to the encoder EEPROM
through P4.97.
2. Mask this fault through P4.98.
The motor parameters in the drive
EEPROM are used for
initialization.
Er02-d
Encoder fault–Encoder
EEPROM data check
error
If the motor is used with a
communication encoder, a
data check error occurs
when the motor attempts to
read data from the encoder
EEPROM during power-on.
1. Ensure encoder cables are
connected properly and eliminate
the conditions that disturbs
encoder communication.
2. Select the motor model based
on the setting of P0.00 and
execute the operation of writing
data to the encoder EEPROM
through P4.97 so that data in the
encoder EEPROM is updated.
3. Mask the this fault through
P4.98. The motor parameters in
the drive EEPROM are used for
initialization.
Er03-0
Current sensor fault–
Phase-U current sensor
1. The current sensor or
detection circuit is abnormal.
Repower on the motor shaft in
static state. If the fault is reported
